IMPROVEMENT IN BINKS.

TO'4 ALL WHOM ITMAY CONCERN:

Be it known that I, HUGH II. CRAIGIS, ot` the city and State of New.Yorin-have invented, made, and

applied to use a certain nen and useful Improvement in Sinks; and I dohereby declare the kfollowing to be a full, clear, and exact descriptionof the said invention, reference 4'being had to the annexed drawing,making part'of this specification, \vhereinp Figure 1 is an invertedplan of the'sink; and

Figure 2 is a vertical section'atthe line a: 2:, showing the trap andpipe.

Similar letters denote the same parts. l

Sinks have heretofore been i'ormed with a bent pipo to retain water andform a trap to the sewer pipe.. This is liable to become choked, and,being ot' necessity some little distance below the sink, is liable toinjury from poils, pots, or other kitchen utensils that arfe oftenplaced in a closet that is formed under thcsink. In makingl theattachment between tbe iron ferrulc and the lead pipe a flange withbolts and nuts has usually been employed; but this device is costly andunsightly.`

The nature of my said invention consists in a trap formed by a cupattachedto the under sideof the sink,

into which a fen-,ale from the sink passes, and terminates below thewater line in said cup. y The escupe pipe `passes o' from the side ofthis cup `in the form of o bond, so that the pipe to the sewer can 4hevertical and close against the wall; and I unite the iron and lead pipoby dressing the soft-metal pipelinto a contraction or neck in the ironpipe and driving over it a metal ring, which makes ahvcryrstrong, tight,and nent joint, because the neck receiving the soft-metal pipe preventsthe joint becoming loose by concussion or strain, because the pipecannot draw o said neck neither can the iron pipe slide further into thelend pipe, the neck holding thegpipes together, and preventing amovement in either direction.

In the drawing, a represents the sink, of any desired size` or shape; bis a ferrule formed below the grating or strainer v, and d isthe cupforming the trap. This cup is attached to the under side of the sink bymeans of wedge-shaped lugs e e cnteringbetn'een lips or projections uponthe under side of the sink.` fis the bend passing oft' from the side ofthe cup d, and terminating near the back of the sink, so that the pipeg, leading to a cesspool or sewer, .may stand vertically, or nearly so,against the wall or support against which the sink is placed. The pipe gis attached to -thc iron pipe f by thesaidppef being entered within theend of the pipe g, the ring h being tirstlipped on. The soft-metal pipeq is then hammered or pressed down into a recess or neck, i, around theend of the pipe and the ring driven over the end of the pipo g, securesthe parts firmly and tightly togethcr. p

What I claim, and desire to secure by LcttersPatenqis- A l. A trap forsinks, foruicd by the detachable cup d, attached to the under side ofthesink, in combination with the downnarlbprojecting ferrule or pipe b, asand for thepurposes set forth.

2. I claim the bendf and trup d; in combination with the stift-metalpipe g, connected to the bend f by the ring l; and neck, substantiallyas and for the purposes set forth. f t

In witness whereof I have hereunto set my signature this 19th day ofJanuary, A. D. 1867.

HUGH H. CRAIGIE.
